CARL/E. SII-IIELDS, OF ROCK ISLAND, ILLINOIS.

BENCH-VISIE SUPPORT.

To all 'whom it may concern: v

Be it kno-wn that I, CARL E. Si-IiELns, a citizen of the United Statesof America, and resident of ItockIsland, Rock Island county, Illinois,have invented a certain new and useful Improvement in Bench-viseSupports, of which the following is a speciiication.

My invention relates to a bench vise, and more particularly in animproved means of supporting the same. D

More particularly, my invention relates to means for so supporting avise that it can be angularly rotated and locked in any desiredposition. These and other ob]ects of my invention will be more clearlyunderstood by reference to the accompanying drawings, in whichn Figure 1is a side elevation of a supportand vise, part of the support beingshown in section. Fig. 2 is a plan view of 1, showing in dotted linesanother position for the vise. Fig. B is a bottom view of the support.

In the drawings, like reference characters refer to like parts.

I have shown my invention in connection with a vise consisting of astationary )aw 1.,I supported upon the standard 2,. and the movable jaw8 supported by the tail-piece 1. The movable jaw is adjusted withrelation to the stationary jaw by means of the threaded rod 5 andoperating handle 6 in a manner well understood in the art.

The bottom of the standard 2 terminates in a circular base 7 which restsupon a suit able supporting base S, which is securely attached to abench or the like by means of bolts 9 passing through the ears in saidsupport. Passing through the center of the base 7 and support S is apivot bolt 10 (see Fig. 3), having a suitable head 11. This bolt acts asan aXis about which the base 7 can revolve, as will be readilyunderstood. In order to lock the base in any desired relative positionon the supporting base, I provide the following means.

The rear portion of the standard 2 is rec-- tangular in cross-section,so that the circular base extends beyond it at the two sides, as clearlyshown in Fig. 2. rThe support is provided with a semicircular slot 12,`as shown in Fig. 3. There is likewise a circular hole in the basethrough which the bolt 13 passes, said bolt likewise passing throughSpecification of Letters Patent.

said slot 12. The boltis provided with a suitable head let, and isthreaded upon the opposite end, which projects through and abo-ve thebase 7. Upon this upper portion is a threaded clamping member 15 fromwhich projects the operating arm 16. This arm. can be rotated through anangle of about 1800, which movement rotates the clamping member 15 onthe threaded bolt 13.

The face of the clamping member 15 is cam-shaped. As shown in Fig. 1,the side of the clamping member on the side of the arm 16 is thickerthan the opposite side thereof. The upper surface of the base 7 islikewise provided with a cam-shaped projection 17 adapted to engage withthe camshaped face of the member 15. As shown in the drawings, the arm16 is thrown to the right, in which position the cam-shaped projection17 bears against the thinnest part of the clamping member 15. Therefore,in this position the base 7 is not securely clamped to the support 8and, if it is de sired, the base 7 and with it the whole vise can bereadily rotated, the base 7 pivoting upon the pivot bolt 10, and theextent of rotation being limited only by the length of the slot 12 inthe support 8, as it will be seen that as the base is rotated the bolt13 travels along this slot. I/Vhen it is desired to lock the vise in anyposition it is only necessary to rotate the arm 16 through an angle ofapproximately 1800. As the thick portion of the cam-shaped clampingmember 15 rides up upon the cam projection 17, the base 7 is forceddownward into firm and secure frictional engagement with the support 8,thus firmly clamping the vise to this support and securing it inposition. It will be noticed that this clamping action is aided by thefact that the clamping member 15 being threaded upon the bolt 13, whenthis member is rotated in the manner above described the whole member iscarried downward slightly by this threaded engagement into frictionalengagement with the support.

It will thus be seen that I have devised a simple and efficient devicewhereby a vise can be readily moved to any angular position and clampedin that position.

While I have illustrated my invention in connection with a bench vise,it is to be understood that I do not wish to limit myself to such use,but
